CHARLES O. YALE, OF NEW YORK, N. Y.

SAFE.

SPECIFICATION forming part of Letters Patent No. 488,803, dated December 27, 1892.

Application tiled March,25,1892. Serial No. 426,354. (No model.)

To a/ZZ whom t may concern:

Be it known that l, CHARLES O. YALE, of

' the city, county, and State of NewYork, have invented certain new and useful Improvements in Burglar-Proof Safes; and I do hereby declare that the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and t0 the letters and figures of reference marked thereon,which form part of this specification.

My present invention relates to improvements in burglar proof vaults, and more particularly to that class of vaults which are formed of railroad iron, although this particular form of iron is not essential.

Similar letters and numerals of reference refer to the same parts in the several figures.

Figure 1 shows in perspective, the inside upper corner of a vault constructed according to my plan and illustrating the present improvements. The figure also shows a cross section of a portion of the top and side of the vault. Fig. 2 shows a section of the wall and top or bottom (the construction being the same) taken on a line at right angles to the lines on which the section portion of Fig.1 is taken. The line on which the section is taken follows the contour of the rails through the top or bottom, as the case may be. Fig. 3 shows on a smaller scale, a blank from which a corner piece, illustrated in Fig. 1 is formed, the blank being bent at right angles on the dotted line to form the corner pieces. Fig. 4 shows a horizontal section of a corner of the vault, the section line following the contour of the rail through the Wall showing the rail in plan view from the side.

Referring more specifically tothe reference letters and numerals marked on the drawings, A and A indicate the rails of which the side walls are formed, having the Webs of the rails toward the outside and inside of the walls respectively.

B, and B are the rails of which the top is formed having the web portion of the rail to the outside and inside of the vault respectively. The vault may be built with its side walls start-ing directly from a suitable foundation, or the Vault may be provided with a bottom constructed in the same manner as the top, therefore the description will be made of the top only. The side walls are constructed with rails A, and A which are laid up with the heads of the rails projecting alternatively in opposite directions, the rails being bent at the corners, or angles of the vault, as shown in Fig. 4 thus forming a strong corner without joints in the horizontal plane of the vault. The rails of the walls are laid up with cement or some suitable composition or material. as illustrated in the open section lines at 1 which completely fills allthe spaces between the rails. The roof of the vault is formed similarly to the side walls bylike rails having their heads projecting in alternately opposite directions and having intervening spaces lled with cement, as described with reference to the Walls. The rails 2 and 3 adjacent to the corner of the Vault have their heads lying inward and the Web to the outside and the heads are mitered as shown at a: forming a complete joint. t

Between the Webs of the rails 2 and 3 is provided an angular corner piece 4 which is provided with webs extending to the rails 2 and 3 respectively, and adapted to engage on the inner face of the web of the rails and preferably conform in shape thereto. The liange or web of the corner piece is secured to the flange or web of the rail by screws 1nserted from the inside as shown at 5" (Fig. 2). Between the angle of the corner piece 4 and the mitered heads of the rails 2 and 3 is 1ntroduced a T- shaped bracing rail 6, the web of which engages in the angle of the corner piece and the head on the sides of the heads of the rails 2 and 3.

On the inside corner formed by two adjacent sides and the top of the vault, is provided an angular bracing plate 7 which consists of the portions 7a, 7b, and 7c bent to form a corner and one of which parts lies on the ceiling or top, one on one of the Walls, and the other on the other Wall. The portions 7a, 7b and 7 c rails by screws 8, 9 and 10.

IOO

bracing plate 7 forms a portion of theirst layer of lining which is continuedby plates as 11, 11 which may be placed diagonally on the sides of the vault or horizontally or vertically, as may seem best. Over the first layer of plates may be provided an inner layer composed of plates as 12, 12 which arey preferably7V made to run crosswise, or substantially so, of the other layer. The layer of plates 11 is secured to the rails by screws extending from the inside of the vault outward and the plates 12 are secured to the plates 11 by screws eX- tending from the inside outward. On the outside of the vault is provided one or more layers of plates,preferably of iron orsteel welded, as shown at 13, which plates or covering are preferably bentat the corners and are secured to the rails forming the body of the walls, by screws as-let, 14 inserted through openings in the flanges of the rails A and B and engaging from the linside in screw-threaded openings in thefplates.

The several courses of laminated plates may beV provided on the outside of the vault aswell as on the inside.

Around the -whole vault is preferably constructed a covering of .masonry-in the-.usual manner. whichengages on the ends of therails Brand B forming the top of the vault is tted thereto by having the ends of the rails B and B `cut withv a projecting lipas shown at 15 (Fig. 2), to adapt the rail to engage with the corner piece 4. It will be observed ithatth-e alternate rails A and A ofthe sides and B and B of the top do not extend ,through from the plating of the inside to the plating ofthe outside but that Atheheads of therails interlock andare so held by the cement llingthe interstices between the heads and webs of the rails.

What I claim as new and desire to secure by Letters Patent, is

1. The combination in a safe .vault having the walls thereof formed of bentheaded in- That portion of the wall of the vault terlocking T-shaped rails, of the corner rails thereof having the inwardly projecting heads contiguous to and adapted to engage each other, an outside corner or truss piece having projecting webs adapted to engage and be secured to the web of the rails, a bracing piece between the angle of the corner piece and the heads of the corner rails and inside corner plate having three integral portions adapted to engage two or more of the rails of the three adjacent sides to the corner and forming a portion of the inside casing and the outside casing, the outside and inside casings being secured to the compiled rails by screws introduced from the inside through the web ofthe rails and through the casings, substantially as set forth.

2. The combination in a safe vault formed of interlocking metal rails having the heads o f the rails adjacent to the corners engaging eachother, anangular truss corner piece having its webs conforming inoutline to and engaging ontheinnersurface of the websof the .corner rails and secured thereto and-a bracingipiece introduced between vthe-engaging heads. of the cornerrails and the ytrusscorner piece, substantially.. asset forth.

3. The combination in a safe vault having its Walls composed of compiled rails of an inlside corner piece formed of one sheet of metal and having three tapering portions `bent to engage the threeadjacent walls of the corners Vand securedto the rails and forming a portion of the insidecasing composed of plate or sheets -fitting ontothe tapering wings or portions of CHARLES O. YALE.
